SASH-CORD HOLDER.

SPECIFICATION forming part of Letters Patent No. 570,631, dated November3, 1896.

Application filed J' une 22, 1896. I

To all whom it may concern:

Be it known that I, CHARLES U. HANNUM, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in Sash-Cord Holders, of which the following is a specification.

This invention relates to a new and useful improvement in sash-cordholders, and has for its object to provide a simple means whereby theends of such a cord may be clamped and the leader-chain passed over thepulley, so as to draw the cord to its proper position within thewindow-sash through the pocket-opening, when the weight may be attachedthereto.

With this end in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth, and thenspecifically designated by the claim.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, its constructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which-Figure l represents the end of a sash cord or rope having thisimprovement applied thereto, and Fig. 2 a detail central section of thedevice.

In carrying out this invention a clamp is provided which consists of twohalves A, hinged together at B by a suitable pin. These halves when intheir closed position form a hollow tapering ferrule which is socorrugated as to serve as ascrew upon which the thimble or nut C may berun, and as the clamp is made of thin sheet metal, preferably stampedinto shape, it follows that the inner surfaces of each half is alsocorrugated, but reversely from the outer surfaces thereof, and theseconcaved corrugations are of such pitch as to match the convolutions ofthe intertwined strands of the rope or cord, as clearly shown Serial No.5 96,475. (No model.)

in Fig. l. From this it will be seen that when it is desired to securethe clamp to the end of a sash-cord it is only necessary to back 0E thethimble C, spread the halves of the clamps sufciently to embrace the endof the rope, again closing said halves against the rope, and nally runthe thimble upon the convexed'corrugations of the clamp toward thelarger end thereof, thereby gradually drawing the halves toward eachother until they take a firm hold upon said rope, after which theleader-chain, (not shown,) which has previously been attached to thelink D, through which the pintle B passes, is passed over the ordinarypulley and permitted to drop within the hollow in the casing untilregistering with the pocket, through which it is drawn until access hasbeen gained to the end of the rope, after which the thimble may bebacked off of the clamp, the latter removed from the rope, and said ropeattached to the weight in the usual manner.

Having thus full5r described this invention, what is claimed as new anduseful is- A ropeclamp consisting of two halves stamped from sheet metaland hinged together at one end to form a tapering ferrule,

the ends of said halves being flared at the hinged end, said ferrulebeing corrugated in concave-convex form to form a screw, saidcorrugations extending through to the inner surface of the ferruleforming concave corrugations and being of a pitch to match theconvolutions of the strands of the rope, a nut threaded to match theconvex corrugations and adapted to clamp the two halves together,

a link passed over the pintle of the hinge, as

and for the purpose described.

In testimony whereof I have hereunto afxed my signature in the presenceof two subscribing witnesses.

CHARLES U. IIANNUM.
